Herdr Code Review

Delegate a code review to a fresh coding agent started in a new sibling pane of the current Herdr workspace. The spawned reviewer executes the team-code-review skill end to end and returns its report in the pane. This skill owns only the handoff and the reviewer lifecycle; it does not perform the review itself.

0. Decide whether to delegate

Before spawning anything, verify delegation is actually wanted:

test "${HERDR_ENV:-}" = 1

• Not inside Herdr: say that Herdr control is unavailable and run the team-code-review skill in the current agent instead. Do not attempt Herdr commands.
• Already the delegated reviewer: if your current assigned review pass explicitly contains the marker HERDR_CODE_REVIEW_REVIEWER=1, you are the spawned reviewer, not the caller. Do not spawn another agent; execute team-code-review directly and return the report where it was requested. This prevents recursive reviewer spawning even if this skill is loaded by mistake.
• User wants the review in the current agent: run team-code-review directly without this handoff.
• Inside Herdr and delegation is requested: continue below.

Every new review or re-review requires a fresh agent session, including reviewing fixes or repeating an unchanged target. Never send a new pass to the old reviewer or resume its session. If a new pass is requested directly in the reviewer pane, hand control back to the original caller for replacement; do not close your own pane or review again in the existing context.
